Bug Fix Advisory

Topic

Updated spice-vdagent packages that fix several bugs and add various
enhancements are now available for Red Hat Enterprise Linux 6.

Description

The spice-vdagent packages provide a SPICE agent for Linux guests.

The spice-vdagent packages have been upgraded to upstream version 0.14.0, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#951596)

Bug fixes:

• While adjusting the guest's monitor configuration, the SPICE guest agent could
  fail to set the resolution when it switched to full-screen mode, which left the
  guest's monitor configuration in an inconsistent state. This happened because
  the agent did not handle situations when the guest's video memory was exhausted.
  This update fixes the issue by reverting the guest's monitor configuration to
  the previous state when the agent fails to adjust the guest monitor
  configuration. (BZ#881020)
  
• The SPICE guest agent previously expected the guest's monitor configuration to
  be always continuous, and attempted to establish and maintain connections with
  display windows in ascending order (that is display 1, 2, 3, ...). The user was
  thus unable to open displays out of order and choose which display would be
  closed when closing a display window. The problem has been fixed by sending a
  sparse monitor configuration to the agent, which allows specifying of the
  display that is to be open or closed. Monitors to be disabled are configured as
  0x0 sized monitors in the sparse monitor configuration. (BZ#894036)
  
• The user session spice-vdagent process could terminate unexpectedly when the
  spice-vdagentd daemon was restarted after performing certain tasks such as
  resizing the window, copying and pasting data and changing to full-screen mode.
  This happened because the SPICE guest agent attempted to free already-freed
  memory upon a spice-vdguestd restart. The agent now frees the memory correctly,
  and the user session spice-vdagent process thus no longer crashes in this
  scenario. (BZ#894365)
  
• The SPICE guest agent for Linux logged warning messages when using multiple
  monitors per single qxl device, which is unnecessary since spice-vdagent
  supports such configurations. The spice-vdagentd daemon has been modified so the
  warning messages no longer occur in the log. (BZ#895004)
  
• When running the SPICE guest agent on the system without the virtio channel,
  the agent emitted inadvertent error messages about a missing virtio device. This
  update fixes this problem by removing the respective syslog() call from the code
  and the error messages no longer occur in the system log in this situation.
  (BZ#999804)
  
• When the user reconnected to a remote-viewer window after closing it while
  copying a large amount of data from the client to the guest, the copy-paste
  function stopped working. Furthermore, the user were unable to call the context
  menu by clicking the left mouse button. This happened because the SPICE guest
  agent did not release the clipboard in this situation. The agent has been
  modified to properly release clipboard and the problem no longer occurs.
  (BZ#1003977)
  

Enhancements:

• The SPICE guest agent now provides support ensuring correct translation of
  end-of-line sequences when the client run on different operating system than is
  the guest's operating systems (for example, when running a Windows client and a
  Linux guest). (BZ#799482)
  
• This update adds support for setups with multiple X11 screens. Such a setup
  can be achieved using multiple qxl devices where each device is mapped to a
  separate screen. This setup brings the following limitations: only one monitor
  can be used per X11 screen (a qxl device), all monitors must have the same
  resolution, and resolution synchronization has to be done on guest machines
  since no SPICE client is present. (BZ#904082)
  
• A new "-X" command-line option has been added to spice-vdagent, which allows
  disabling the ConsoleKit framework and the systemd-logind service integration at
  runtime for setups where these services are not used. (BZ#904084)
  

Users of spice-vdagent are advised to upgrade to these updated packages, which
fix these bugs and add these enhancements.
